I had a quick experiments with some of these idea in case there is interest:

The key difference in this approach is that the functions go first, and
work as regular functions. If you get a chance take a look and let me know

I would be very interested in your code. Awhile back I did add support for
most enlive selectors to enfocus. So you can use something like [:td
:#id1] in your enfocus templates. This does have limitations though. I

It might be useful, though, to be able to enable warnings for shadowed
variables.

The big advantage to my reorganization of your loop is that it doesn't have
an unused "x" binding.
The other advantage is that the expressions bound to "x" and "y" are not
repeated at the beginning of the loop and at the end.

I have been working on a library for ClojureCLR that actually uses a
Clojure DSL to generate, compile, and load C code live into a running REPL.

You're actually probably better off using clojure's reflector
(clojure.lang.Reflector/invokeStaticMethod ...) or
(clojure.lang.Reflector/invokeInstanceMethod

That way you get type coercions that match clojure's behaviour.

Additionally I'd like to note that it's not strictly necessary to have IF

You can build IF out of thin lambda, by defining TRUE as a function calling
